FLOOR DRAIN.

Application filed January 2, 1926, Serial No. 78,835

This invention relates to floor drains of the type that comprise a.stationary member imbedded in the floor below the top surface of thefloor and having a drain pipeconnected to same a vertically adjustablehead piece carried by said drain pipe member and provided at its upperend with a grille or grating which extends flush or substantially sowith the top and a flashing formed usually by a sheet of lead or othersuitable water-proof element imbedded in the floor below the top surfaceof same and connected to said drain pipe member in such a manner as tointercept and collect any water which seeps down around the exterior ofthe head piece of the drain.

The main object of my invention is to provide a floor drain of thegeneral type referred to, which is of such construction that thestationary member of the drain and the waterproof element thatco-operates with said member can be combined quickly and easily in sucha manner as to eliminate the possibility of seepage finding its way intothe foundation layer of the floor in which said stationary member isimbedded.

The figure of the drawing is a vertical sectional View of a floor drainconstructed in accordance with my invention.

Referring to the drawing which illustrates the preferred form of myinvention, A designates the stationary member of the drain which mayconsist of a trap or a straight tubular member to which a drain pipe Bis attached, m designates the foundation layer of the floor in which themember A is imbedcled, z designates the finishing coat or top layer ofthe floor, C designates a water-proof element formed usually from a thinsheet of lead that is arranged horizontally between the foundation layera: and top layer 3 of the floor adja cent the upper end of the member A,and D designates the vertically-adjustable head piece of the drain whichis provided at its upper end with a grille or grating 1 that extendsflush or substantially so with the top surface of the floor.

In structures of the character referred to it is essential that thewater-proof element 0 be connected with the stationary member A of thedrain in such a manner that any seepage which collects on the element Ccannot escape into the foundation layer 00 of the floor and in order tobe successful from a commercial standpoint, the drain must beconstructed in such a manner that the water-pri'iof element C can becombined with the member A quickly and easily. Accordingly, I haveprovided the stationary member A of the drain with a clamping ring Ethat serves as a support for the head piece D of the drain and which isadapted to be manipulated so as to clamp the water-proof element Ctightly against a portion at the upper end of the stationary member Aherein illustrated as a laterally-pro- 'ecting flange. 2. The clampingring E is preferably screwed into an internally-screwthreaded portion atthe upper end of the member A, and said ring is provided with alaterally-projecting flange 3 that laps over the water-proof element Gand forces said element downwardly against the upper end of the member Ewhen said ring is tightened by screwing it down into the member A. It isimmaterial, so far as my broad idea is concerned, how the head piece Dof the drain is supported 011 the clamping ring E, but I pre fer toprovide said head piece at its lower end with an externallyscrew-threaded portion 4 that is adapted to be screwed into internalscrew threads on said clamping ring. To facilitate screwing the clampingring E into and out of the stationary member A of the drain, said ring Eis provided on its top side with lugs 5 which are adapted to beengagedby a bar or tool that is arranged crosswise of said' ring when the headpiece D of the drain is not positioned in said ring.

In installing the drain the stationary memberA is first imbedded in thefoundation layer of the floor and apiece of sheet lead C or otherwater-proof material is then placed over the upper end of said member Aand pressed downwardly slightly into the internally screw-threadedopening in the upper end of said member, so as to mark the element O atthe point where a portion of said element has to be removed to form ahole for the clamping ring E. After this portion of the element G hasbeen cut out said element is again arranged horizontally on the flange 2at the upper end of the stationary member A and the clamping ring E isthen screwed into said member A, so as to cause the flange 3 on saidring to clamp the element C tightly against the upper end of the memberA. The flange 8 of the clamping ring E is then connected to thewater-proof element C by a soldered joint 6, so as to eliminate thepossibility of any water which collects on the element C seeping throughthe joint between said element and the flange 3 of the clamping ring andeventually working down into the foundation layer of the floor.Preferably, the peripheral edge of the flange 3 on the clamping ring Eis beveled so as to permit the water-proof element C to be connected tosaid flange quickly and easily, simply by running a soldering ironaround the beveled edge on said flange. After the head piece D of thedrain has been screwed into the clamping ring E, the top layer orfinishing coating ot the floor is applied. thus completelyconcealing theWaterproof element C and encasing all of the head piece D of the drain,except the top edge of same and the grille 1 that is mounted in saidhead piece.

A floor drain of the construction above eescribed etl'ectix' elyprevents water from seeping down into or through the ioundation layer ofthe floor, and it is inexpensive to manufacture and easy to install.

Having thus described my invention, what I claim as new and desire tosecure by Lettors Patent is: V

A floor drain, comprising a member that is adapted to be imbedded in afloor below the top surface of same a laterally-prejecting flange at theupper end of said member, a waterproof element supported by said flangea. clamping ring arranged in o 'erlapping relation with said water-proofelement and provided at its inner edge with a depending,externally-screw-threaded portion that is screwed into said member, abeveled surface at the peripheral edge of the portion of said ring whichlaps over the water-proof element, adapted to be connected to saidwaterproof element by a soldered joint, upwardly-projecting lugs on thetop side of said ring adapted to be engaged bya device arrangedtransversely of the ring that is being; used to screw the ring into saidmember, and a verticallyadjustable head piece mounted in said clampingrin JOSEPH Cv SANDERS.
